A Cedar Hill ISD middle school teacher was arrested Wednesday after accusations that she had sexual relationships with two students.

Marlena Mints, 31, a health teacher and coach at Bessie Coleman Middle School, was charged with two counts of improper relationship with students and one count of aggravated sexual assault.

Another coach reported the allegations after a 13-year-old student told her and other students that he and Mints had had sexual contact in January, according to an arrest affidavit. When the coach told him that the contact was rape, the student replied that Mints was “just a cougar who likes younger men” and that he was “one of her favorites.”

The boy also said Mints allowed him and other students to touch her inappropriately in her classroom, the affidavit stated.

Another arrest warrant affidavit said that police had identified a second potential victim, who told officials that Mints had picked him up from his home during spring break and taken him to her home to perform a sex act.

Cedar Hill ISD put Mints on administrative leave April 30, Cedar Hill city spokesman Corky Brown said. Police issued warrants for her arrest Tuesday and took her into custody after she was stopped for a traffic violation Wednesday.

She was being held in the Dallas County Jail.

Mints has worked for the school district since 2006. District officials said in a news release that they had conducted all legally required background checks on Mints when she was hired.

Mints wrote on her teacher page on the school’s website that she had been teaching health for five years.
